Gerbera plant named ‘Lekgerred’

ABSTRACT

A new and distinct cultivar of  Gerbera  plant named ‘Lekgerred’, characterized by its double-type, red-colored flowers, dark green-colored foliage, and vigorous, upright growth habit, is disclosed.

Latin name of genus and species of plant claimed: Gerbera×hybrida.

Variety denomination: ‘Lekgerred’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gerbera plant botanically known as Gerbera×hybrida and hereinafter referred to by the cultivar name ‘Lekgerred’.

The new cultivar originated in a controlled breeding program in Pijnacker, The Netherlands during May 2007. The objective of the breeding program was the development of Gerbera cultivars that are freely flowering with large flowers.

The new Gerbera cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Gerbera×hybrida breeding line designated AF 83, not patented, characterized by its double-type, red-colored flowers, dark green-colored foliage, and compact-upright growth habit. The male (pollen) parent of the new cultivar is the proprietary Gerbera×hybrida breeding line designated AF 752, not patented, characterized by its double-type, red-colored flowers, dark green-colored foliage, and semi-compact, upright habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during May 2008 in a controlled environment at Pijnacker, The Netherlands.

Asexual reproduction of the new cultivar by tissue culture propagation in a controlled environment since May 2008 at Pijnacker, The Netherlands has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Lekgerred’ as a new and distinct cultivar of Gerbera plant:

-   -   1. Double-type, red-colored flowers;     -   2. Dark green-colored foliage; and     -   3. Vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a growth habit that is not as compact as the female parent. Plants of the new cultivar differ from plants of the male parent primarily in having a flower color that is different shade of red from the male parent.

Of the many commercially available Gerbera cultivars, the most similar in comparison to the new cultivar is Revolution ‘Mega Scarlet DC’, not patented. However, in side by side comparisons, plants of the new cultivar differ from plants of Revolution ‘Mega Scarlet DC’ in at least the following characteristics:

-   -   1. Plants of the new cultivar are more double flowering than         plants of Revolution ‘Mega Scarlet DC’; and     -   2. Plants of the new cultivar are more vigorous than plants of         Revolution ‘Mega Scarlet DC’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Lekgerred’. The plants were grown in 14 cm pots for approximately 11 weeks in a greenhouse at Pijnacker, The Netherlands.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Lekgerred’.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Lekgerred’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined in August 2009 under natural light conditions in Pijnacker, The Netherlands.

The following descriptions and measurements describe plants produced from tissue culture plantlets and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in Pijnacker, The Netherlands in 14 cm pots for approximately 11 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
